those NADH supplement is safe for oral consumption?

[MrSub4]

what happens is the athlete starts running like the wind.

[canuckythe]

can anyone give me a detailed explanation for pyruvate oxidation? How does NAD+ convert to NADH? where does the 2 H atoms come from. When the carboxyl group is removed as CO2, what happens to the Hydrogen? How is the 2 carbon compound after decarboxylation an acetate group. Why is that reaction a redox?

[Blackfiria]

NADH is broken down to NAD+ through the Electron Transport Chain (ETC) and the NADH Dehydrogenase Complex ( the first proton pump in the ETC, it has a higher affinity for electrons and therefore strips the NADH of the 2 high energy electrons and the proton H+, this happens thru out the ETC (search for info on this, thr is alot on youtube) the mitochondria taps into the proton graident from the pumping of these protons and produces ATP from the energy.

Blackfiria, yes I would appreciate an answer.

[Blackfiria]
